What happens when you do no hard-code version numbers?

Everything works fine in this case. But I need R 2.15 -- as you may have 
guessed, this is for r-travis. Here are a few failed builds:

https://travis-ci.org/krlmlr/r-travis/jobs/13630510 -- explicitly 
installing all packages r-recommended depends on

https://travis-ci.org/krlmlr/r-travis/jobs/13630201 -- install R 2.15 
and current r-recommended

https://travis-ci.org/krlmlr/r-travis/jobs/13629522 -- the original 
case: install R 2.15 and r-recommended 2.15

If this can't be resolved easily on the client side: Perhaps this could 
be fixed by (a) adding older deb-s to the repo and/or (b) specifying a 
maximum version in r-recommended?

On the other hand, r-recommended is necessary for CRAN checks, not so 
for "regular" checks against older R versions.

What does, say, 'apt-cache policy r-recommended' say?

It aims at installing the most recent version, I guess. I have fired up 
another build to check this:
